Filed July 26, 1961, Ser. No. 126,992 3 Claims. (Cl. 161-26) This invention relates to machines for drilling hole in and spot marking fabric and more particularly to a machine for drilling small holes in a pile of many layers of cloth and simultaneously applying a powder mark around the edges of each hole.

In the manufacture of clot-hing and similar articles, cloth is laid in many layers, one on top of the other, and in one cutting the manufacturer cuts a number of identical sections. It is necessary to mark these sections in order to conform them to the pattern and to indicate where certain tailoring details, such as pockets, buttons, buttonholes or ornaments are to be placed.

Heretofore this marking has been done by placing a thread through the pile of the material at the desired spot.

This method has its obvious disadvantages and limitations. Marking has also been done by drills which used a wet needle and which would leave a slight stain at the spot where the button or other ornament was to be placed. This method is objectionable in view of the stain left on the cloth which in many fabrics cannot be easily removed.

A principal object of the present invention is to provide a machine with a drill which will perform the functions indicated by leaving a small powder mark around the hole which is drilled in the fabric.

Another object is to provide a machine of this type with means for indicating the angular position of the drill relative to the top of the table supporting the fabric.

Still another object is to provide means on the machine for adjusting the length of downward movement of the drill through the fabric.

A further object is to provide the machine with means for resiliently mounting the drill support and motor.

Yet another object is toprovide the machine with means for guiding the point on the stack of fabric relative to the drill.

It is also proposed according to a modification of the invention to provide a resilient mounting for the container for the marking substance.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

FIG. 9 is a top plan view of the sleeve bearing member with the spring pressing plate and cap removed.

FIG. 10 is a top plan view of a section of :a piece of cloth showing the manner in which the drill marks the cloth.

A cloth drill made in accordance with the preferred form of the invention is shown in FIG. 1 and is designated generally by the reference numeral Ill. The drill 10 comprises a flat triangular-shaped base 12 of metal. A-n upright round hollow post 14 is supported in a socket bearing 16 at one corner of the base and is held in place by set- -screws 13. The post is open at the top and is formed with opposed elongated slots 20 that extend from apoint closely spaced from the top of the post to a point midway the ends thereof. The open top is closed by a removable cap 22.

A sleeve bearing member 24 is slidably mounted on the top end of the post and extending perpendicularly from the top of the sleeve bearing is an integral radial crossbar 26 terminating in a ring-like socket bearing 28. A perforated plate Iatl is supported on the top end edge of the sleeve bearing 28 around the post lid and is secured thereto for movement therewith by means of screws 32 engaged in threaded openings 33.

A conventional electric motor 34 extends through the ring-like bearing 23 and is fastened thereto and supported thereby in vertical arrangement by screws 36. A chuck member 38 is fastened to the bottom end of the depending motor shaft 40. A solid needle 42. is held suspended in the chuck member in the usual manner. The outer periphery of the needle is longitudinally slotted or fluted as indicated at il (FIG. 6). The needle may have one or more flutes 41, four being shown. A single helical shape flute may also be used. The needle is pointed at its lower end 44. An electric switch 46 is positioned on the crossbar 26 for controlling the how of current to the motor 34 through conductors 48, 48.

The drill 1ft is provided with the usual table 50 upon which a layer of fabric sections 52 is supported for operation thereon by the drill.

The base 12 is formed with a circular opening 54 offset from the center thereof. On the top of the base at one side thereof between the corner mounting the bearing member 16 and an adjacent corner there is a curved bracket or arm 56 terminating in a ring-like bearing 58 positioned over the opening 54. The bearing 58 supports a guide sleeve 6% which is clamped therein by a setscrew 62. The bottom end of the needle 42 passes through the guide sleeve 60 on its way to the fabric pile and such sleeve acts to prevent undue flexing or bending of the needle such as might otherwise tend to take place when the fabric pile is especially thick or resistant to piercing and/ or when the needle tends to flex under heavy load in the absence of a guide.

A guide bar 64 having a pointed end 66 and a handle end 68 is slidably mounted on the top surface of the base. The bar 64 has an elongated closed slot 68 with a bolt and wing nut assembly 70 whereby the bar may be moved toward or away from the guide sleeve 60 and held in moved adjusted position. The guide bar 64 coacts with the guide sleeve 6% to accurately place the needle 42 over the marked spot on the pile of fabric, the pointed end of the bar 64 being placed directly over said spot.

A pair of spirit levels 72 and 74- are suitably mounted flatwise on the top surface of the base 12 adjacent one corner, the levels being arranged in right angular relationship in order to indicate when the base is truly horizontal.

The sleeve bearing 24 is normally held in topmost position on the post M by means of a metal crossbar 76 extending across the space in the post with its ends 78 extending outwardly through the slots in post 14 and tapered. The bar 76 rests on the topmost coil of a coiled compression spring 80 which has its other end seated on the top surface of the base 12. The spring presses the ends 78 of the crossbar 76 against the undersurface of the plate 3-!) preventing downward movement of the sleeve bearing and its associated parts. A split ring 82 adapted to be slidably and adjustably supported on the post 14 below the sleeve bearing 24 limits the downward movement of the sleeve bearing and associated parts. The ring 82 is held in adjusted moved position by a bolt and wing nut assembly 84.

The invention also contemplates marking the edge of the drilled hole in the fabric sections with a substance such a powder. For this purpose, a powder chamber constituted by a funnel 86 is supported on the ring-like bearing member 53 of the bracket or arm 56. This funnel has a conical-shaped hollow body 88 terminating at its lower narrow end in a straight downwardly extending flanged neck 90 frictionally mounted on the top end of the guide sleeve 69. The wider top end of the body 38 is closed by a circular fiat plate cover 92, pivotally and swingably mounted on the body 88 by means of a pivot pin 180 passing through a radial lug 94 fastened to a similar lug 96 on an annular radial flange 98 on the top of the body 88. A radially protruding lug 102 on the opposite side of the cover 92 serves as a handle for swinging the cover to open and closed positions. The cover is swung in a horizontal plane as viewed in FIG. 1, a curved slot 104 in the cover intersecting the periphery thereof permitting this operation.

In operation, the powder chamber or compartment 86 is filled with marking material such as luminous or phosphorescent powder 105 or any other powdered or liquid substance suitable for making, through the opening in the top. The base 12 is placed upon the sections of fabric 52 to be marked, in a truly horizontal position with the pointed end 66 of the guide bar 64 directly over the mark on the pile of fabric denoting the place to be drilled. The motor 34 is started by closing the switch 46. The hearing sleeve 24 and motor 34 are manually pressed downwardly by manual pressure on the crossbar 26 against the action of coil spring 80 in sleeve bearing 24. The needle 42 is moved downwardly through the slot 184 in cover 92 and through the funnel 86 and guide sleeve 60. In moving through the funnel, the powder therein falls into the elongated slots 41 in the needle 42 and is carried by the needle outwardly of the guide sleeve 60 and through the layers 52 of fabric where it is deposited around the holes drilled therein by the needle, leaving a colored ring 108 around the hole 110 drilled in each layer 52 of fabric.

It will be appreciated that the downward motion of the sleeve bearing 24 and motor 34 with needle 42 will be stopped at any predetermined point by the ring 82 on post 14. The sleeve bearing member 24 and motor 34 are manually retracted to upper inoperative position as shown in FIG. 1.

In FIG. 7, a modified manner of mounting the funnel 86 is shown. In this mounting, the ring bearing 58 of the bracket or arm 56 is formed with an upstanding annular flange 112 around the opening therein, which flange is internally screwthreaded to receive the externally screwthreaded flange 90' on the body 88' of the funnel 86'. In all other respects, the mounting is the same as the mounting of the funnel 86 and similar reference numerals are used to indicate similar parts.

Another modified manner of mounting the funnel 86 is shown in FIG. 8 wherein in place of a single arm or bracket such as the bracket 56, a pair of upstanding rods 110, 110 are mounted in socketed openings 112, 112 in the base 12" on opposed sides of opening 54", and resiliently and slidably supported on the rods is a crossbar 56" having circular enlargements 114, 114 on the underside of its ends. The enlargements are formed with recesses 116 to receive and form seats for the upper ends of compression springs 118 sleeved around the rods, the bottom ends of the springs seating upon the top surface of the base. In this form, the guide sleeve 60" is frictionally supported in a round hole 123 in the crossbar midway its ends. In all other respects, the mounting of the funnel S6 is similar to that shown in FIG. 1 and similar reference numerals are used to indicate similar parts.
